This is a little addition for the great rugged box from @Pjotr

it holds the TS100/101 Soldering Adapter + Tips Set from @CNC Kitchen for the TS100/TS101/Pinecil

the dimensions of that “insert base” fitted to my print, probably you have to glue it down or scale a bit, depending to your printer/accuracy

for the insert-center you need some M5 Wormscrews, i used 20mm long screws

the thread in the center holds the worm screws, the tips can be easy screwed on/off

to get the parts out you can remove the complete insert and unscrew the one you need
